What is PC133
PC133 is the la test memory stan dard, increasi ng bus speeds 33 % when compared to the PC100. In the past, 133MHz speed was only available when users overclocked their system. But users have previously found that they could not overclock their system to 133MHz successfully due to set CPU, chipset and memory restrictions. The highest CPU FSB clock was 100MHz. C hi psets an d me mo ry also only s uppor ted u p to a 1 00MHz sy s tem bus cl ock. The 133MHz CPU front side bus is now available and the memory standard has been advanced to the higher 133MHz speed. The 133 MHz system is now ready for market.
What is SoftMenu™ III technology?
SoftMenu™III is ABIT’s newest BIOS offering. The ABIT SoftMenu™III technology not only lets users configure CPU settings easily, but also allows the user greater freedom in the setting of the CPU FSB (Front Side Bus) clock settings.
How does SoftMenu™ III help to provide a more stable PC133 system
ABIT Sof tMe nu™III pr o v ides the user with mor e CPU setting items, including settings for I/O voltage, PCI/CPU FSB Clock, AGP/CPU FSB Clock, AGP Transfer Mode and 120 settings for the FSB clock. All of these setting items are adjustable, thereby giving the user the power to adjust, according to system demands. This gives the user more choice and flexibility while r unning t he 1 33MH z s y ste m bus cl ock on BX mot her boar ds. We w ill de tail these sett ing items in the f o llowing.
!
! Unlimited Front Side Bus (FSB)
!!
In addition to the defaul t setti ngs fo r each proce sso r speed, S oft Menu™I II pro vides 12 0 user-defined settings on the FSB clock. Settings are at 66, 75 and from 83 to 200 MHz.

The settings fr o m 83 MHz to 200 MH z can be alter ed in increm ents of 1, giv ing the user the power to find the best FSB setting, resulting in the best system performance. This technology equips ABIT’s products w ith the most fle x ibil ity and greatest compat ib il ity to current and future specif ications.
!
! CPU Multiplier Factor
!!
From 2 to 8 (Increment 0.5). A total of 13 sets of mult iplier factors supp ort all current CPUs and allows for support of future CPUs. The CPU operating frequency equals FSB clock times th e m ultiplier factor.
!
! PCI/CPU FSB Clock
!!
½, 1/3, and now 1/4 is also a sele ction optio n. I t cor relate s with t he CPU FSB clo ck y ou set. For example, if you set the CPU FSB clock to 100MHz and choose 1/3 here, the PCI clock will be 33.3 MHz . We sugg e st y ou cho ose the r atio , w hic h br ing s t he PCI clock as close to 33MH z as possible.
!
! AGP/CPU FSB Clock
!!
1/1 and 2/3 options let the user adjust the AGP clock. We suggest you choose the ratio which brings the AGP clock as close to 66MHz as possible.
!
! CPU Core Voltage
!!
1.3 – 3.5 V manually adjustable but protected by SoftMenu™III from damaging the CPU. If the “CPU Operating Frequency” is not set to “User define”, BIOS will automatically set the voltage required by the CPU.
!
! I/O Voltage Adjustable (8 sets, 3.2-3.9 V)
!!
This function allows the user to adjust the voltage supplied to DRAM, AGP, and the Chipset, thus gr eatly increasing the possibili ty of higher performance. If the “C PU Operating Frequency” is not set to “User define”, BIOS will automatically set the voltage required by CPU.
!
! AGP Transfer Mode:
!!
This function allows the user to determine the capability of the AGP device. Selecting “Default” gives opt i mized p erf orma n c e. The vi deo d ri ver will d ec i d e th e d ata t ran s fer mode automati cally. If the CPU FSB clock exceed s 125MHz, settin g AGP Transfer Mode to “Normal” wi ll result in a more stable system.
!
! In-Order Queue Depth
!!
This item determines the command queue depth between processor and chipset. Selecting “8” gives optimized performance. Selecting “1” results in a more stable system.
!
! Level 2 Cache Latency
!!
This item allows the user to set CPU L2 cache speed. Selecting “Default” gives the most stable performance. Smaller latenc y gives faster performance, but may cause system instability.

Our Suggestion
We strongly suggest that you use our default settings for each processor speed when you want to configure your CPU settings. We meticulously and repeatedly test these default settings. Adopting these settings will give you the optimum system for stability. The following table lists all of the CPU default settings.
CPU Speed FSB Clock PCI Clock / CPU FSB Clock AGP Clock / CPU FSB Clock
233 66 1/2( 33 ) 1/1 (66) 266 66 1/2 ( 33 ) 1/1 (66) 300 66 1/2 ( 33 ) 1/1 (66) 333 66 1/2 ( 33 ) 1/1 (66) 300 100 1/3 (33.3) 2/3 (66.67) 350 100 1/3 (33.3) 2/3 (66.67) 400 100 1/3 (33.3) 2/3 (66.67) 450 100 1/3 (33.3) 2/3 (66.67) 366 66 1/2 ( 33 ) 1/1 (66) 400 66 1/2 ( 33 ) 1/1 (66) 433 66 1/2 ( 33 ) 1/1 (66) 466 66 1/2 ( 33 ) 1/1 (66) 500 66 1/2 ( 33 ) 1/1 (66) 533 66 1/2 ( 33 ) 1/1 (66) 533 133 1/4 (33.25) 2/3 (88.67) 500 100 1/3 (33.33) 2/3 (66.67) 550 100 1/3 (33.33) 2/3 (66.67) 600 100 1/3 (33.33) 2/3 (66.67) 600 133 1/4 (33.25) 2/3 (88.67) 650 100 1/3 (33.33) 2/3 (66.67) 667 133 1/4 (33.25) 2/3 (88.67) 700 100 1/3 (33.33) 2/3 (66.67) 750 100 1/3 (33.33) 2/3 (66.67) 800 100 1/3 (33.33) 2/3 (66.67) 733 133 1/4 (33.25) 2/3 (88.67) 800 133 1/4 (33.25) 2/3 (88.67)
If you want to choose “user define” and configure every setting manually, please pay attention to the following:
First, when you are selecting the “PCI/CPU FSB Clock”, please refer to the CPU FSB clock you set and choose the ratio which brings the PCI clock as close to 33MHz as possible.
Second, when you a re selecti ng th e “AGP/CP U FSB c lock”, please refer t o th e CPU FSB you set and choose the ratio which brings the AGP clock as close to 66MHz as possible.
Finally for the PC 133 system, we r ecommend the sett ing of the “PC I/CPU FSB Cloc k” t o “1/4”; the “AGP/ C PU FSB C loc k ” t o 2/3 ; th e “AGP Trans fer M od e” to “Norm al” ; and th e “In-Order Queue Depth” to “1.”
